Send Base64 encoded data over USSD from Android -

I am trying to program an Android app that sends updates from the phone to my network provider server using USSD . The problem is that to get data from the network server on my web server, I need data in base 64 encoded datagrams. I am trying to send this data to the format * # Where the data is created, this can send me 2 figures in single figures USSD packets.

This is what I have yet

  send private zeros USS digitate (integer data 1, integer data 2) {four [] data 1CharArray = data1.toString ( ). ToCharArray (); Four [] data2harArray = data2.toString (). ToCharArray (); Integer data 1 length = data 1 charity Height * 2; Integer data 2 length = data 2 sec Height * 2; Four [] dataDataGram = new string (PID.Toosting () + data1 lang.tosting () + new string (data 1CharArray)) Kocharaire (); Four [] datadigram = new string (PID.toString () + data2Length.toString () + new string (data2harArray)). Kocharaire (); String USSDED = "* 126 * 5 *"; Byte [] data1ByteArray = new byte [data1Datagram.length * 2]; ByteBuffer.wrap (data1ByteArray) .asCharBuffer () put (data1Datagram). Byte [] data2ByteArray = new byte [data2Datagram.length * 2]; ByteBuffer.wrap (data2ByteArray) .asCharBuffer () Put (data2Datagram). Byte [] base64data1Datagram = Base64.encode (DataBitire, Base64.NO_PADDING); Byte [] base64data2Datagram = Base64.encode (DataBitire, Base64.NO_PADDING); Byte [] dat = new byte [base64data1Datagram.length + base64data2Datagram.length]; Int i = 0; Whereas (i and lt; base64data1Datagram.length - 1) {dat [i] = base64data1 datagram [i]; I ++; } Int j = 0; Whereas (i & lt; dat.length - 1) {dat [i] = base64data2 datagram [j]; I ++; } {Intent ussdIntent = try new intent (Intent.ACTION_CALL); UssdIntent.setFlags (Intent.FLAG_ACTIVITY_NO_ANIMATION); UssdIntent.setFlags (Intent.FLAG_ACTIVITY_NO_USER_ACTION); UssdIntent.setFlags (Intent.FLAG_FROM_BACKGROUND); Uri Uri = Uri Frantparts ("Tele," USSD + DAT, Encoded Hush); System.err.println (URI); UssdIntent.setData (URI); Act.startActivity (ussdIntent); } Hold (exception e) {System.err.println (e.getMessage ()); E.printStackTrace (); }}    
 
 
 with intent. Action_CALL Your base 64 text will be converted to numerical A, B, C to 2, D, E, F3 and so on (default behavior of outgoing client receiver). Therefore, there is no way to send text data through the USSD in Android (at least with standard methods) ...
